Components are views that you can reuse within other views. For example, you can create a reusable menu or calendar, save it as a component, and incorporate it into your other views.
One way to build a component is to create a new navigation bar and save that navigation bar as a component. Select the Page region of your view, and choose Navigation Bar from the Insert menu. In the Insert Options section of the Insert Navigation Bar wizard, select the option Create a shared component containing a navigation bar for use in multiple views, then provide a name for your new component.
You can also turn a view into a component by saving it to the /Themes/Components folder in your DataWeb web application.
